Abstract: GPS作为一种新的结构振动监测工具正受到广泛关注。目前GPS的采样率可达100Hz,可以满足结构振动监测对采样率的要求,但GPS观测量受多种误差源的影响,其测定结构振幅的精度有待进一步提高。将小波分析方法用于隔离观测噪声,并综合利用两种单历元算法的优点,提出一种新的结构振动监测单历元算法。若干试验验证本方法的正确性和有效性。
GPS is becoming an important tool for structural monitoring. As the advent of the receiver with sampling rate as high as (100 Hz), there is no problem in structural frequency monitoring by GPS. But because GPS observation is contaminated by many errors sources, its accuracy needs to be improved to meet small structural amplitude monitoring. In this paper a new single epoch algorithm is presented by integrating wavelet analysis with combined single epoch algorithm to isolate various errors. Several experiments showed that the proposed algorithm is effective and efficient.
